列名或所提供值的数目与表定义不匹配
出错部分代码如下：

C# code

        string title = TitleText.Text.ToString();        string neirong = Request.Form["neirong"];        string beizhu = Request.Form["beizhu"];        string maker = "00000";//Session["UserID"].ToString();        string time = DateTime.Now.ToString();        string insertString = "insert into other_task values('" + maker + "','"+ title + "','" + neirong + "','" + beizhu + "','" + time + "，null，" + "null" + "')";        string sqlString = "Data Source=localhost;Initial Catalog=gsc;User ID=sa;PassWord=123456";            SqlConnection insertConn = new SqlConnection(sqlString);            insertConn.Open();            SqlCommand insertComm = new SqlCommand(insertString, insertConn);            insertComm.ExecuteNonQuery();//此行提示错误

数据库表结构创建脚本如下：

SQL code

CREATE TABLE [dbo].[other_task](    [TaskID] [int] IDENTITY(1,1) NOT NULL,    [Maker] [char](5) NULL,    [Title] [nvarchar](255) NULL,    [neirong] [nvarchar](255) NULL,    [beizhu] [nvarchar](255) NULL,    [tbegin] [smalldatetime] NULL,    [tend] [smalldatetime] NULL,    [finflag] [bit] NULL) ON [PRIMARY]

请问是哪里的格式不对了？datetime的问题还是不能直接用null？
